SOMERSWORTH — A city firefighter was arrested late last month in Barrington and charged with driving while intoxicated.

Parks Christenbury, 37, of Rochester, was stopped at a gas station near the intersection of Routes 125 and 9 when police caught up with him at about 12:20 a.m. on May 25, said Barrington Police Chief Richard Conway.

At the time, officers were acting on a report of a 2013 GMC Acadia driving erratically. Christenbury failed a field sobriety test and later consented to a blood test at Wentworth-Douglass Hospital, Conway said.

The results of that blood test aren’t yet available.

“He was taken into custody, brought to the station and brought to hospital for a blood test and released with a hand summons because we couldn’t locate a bail commissioner,” Conway said Wednesday.

Driving while intoxicated — first offense is a misdemeanor punishable by a fine and loss of license.

Somersworth Fire Chief Keith Hoyle said he was aware of the incident. However, he said Christenbury claims he did not know he had been arrested.

Hoyle declined to comment further until he and other city officials could review the incident.

“We haven’t seen any of the particulars on that yet,” Hoyle said Wednesday. “We don’t have a comment until we see what happened.”

The city has policies and procedures for when an employee is charged with a crime. Hoyle said he would meet with City Manager Robert Belmore once more about the case was known.

Christenbury was charged last year with felony second-degree assault for allegedly strangling someone during an alleged domestic violence incident. He also was charged with misdemeanor assault for allegedly pushing the same person.

The outcome of those two charges was not known Thursday. Phone calls to the Rochester Police Department and Strafford County Attorney’s Office seeking information on that case were not immediately returned.
